The response of a model two-dimensional colloidal glass former to an externally imposed spatially random potential, which acts as a quenched disorder, is investigated using numerical simulations, motivated by recent experiments and also mean field predictions. The external potential induces the onset of the glassy dynamics at increasingly smaller field roughness, with increasing packing fraction of the particulate assembly, and the existence of aging processes within the glassy regime is also observed. Furthermore, along the axis of increasing field roughness, the dynamical slowdown is not correlated to the hexatic order within the supercooled regime.

淬灭随机势的玻璃形成液

使用数值模拟研究了模型二维胶态玻璃形成剂对外部施加的空间随机势的响应，该势能是淬灭性失调，是由最近的实验和平均场预测引起的。外部电位在越来越小的场粗糙度下引起玻璃态动力学的发生，随着颗粒组件的堆积分数的增加，并且还观察到玻璃态内部存在老化过程。此外，沿着增加的磁场粗糙度的轴，动态减慢与过冷状态下的六边形阶不相关。
